Can anyone let me know how much they've seen prices increase?

I was talking to one Dr for the past 4 years, for the entire 4 years the prices only went up $1000 a year but this year they've increased it by 50% which is insane. From $19 000 to $28 000.

Anyone else seen a similar pattern? Or have prices been going down? I thought prices would decrease for LON as other methods have come out and i'm sure the equipment isn't as rare as a few years ago.
